6 Claims.

My invention relates to gas heaters, more particularly that type in which radiant mantles are used for heat distribution, and the objects of my invention are:

B First, to provide a gas heater of this class in which the heat is radiated in all directions sidewise from the heater;

Second, to provide a radiant mantle gas heater that is approximately circular inform so that the heat is thrown out all around the heater;

Third, to provide a` heater of this class with a hood arrangement tending to throw the heat downwardly and outwardly in all directions from the heater;

l5V Fourth, to provide`a heater of this class in which the conventional radiant mantle may be utilized;

Fifth, to provide a heater of this class which draws its air for burning purposes from near the 9U floor and passes it out in circular form upwardly therefrom and a portion of which is directed downwardly in its outward movement from the heater; and

Sixth, to provide a gas heater of this class which durable, efficient and which will not readily deteriorate or get out of order.

With these and other objects in view as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference being `had to the accompanying drawings and to the `characters of reference thereon which form a part of this application, in which:

Figure 1 is a side elevational view of my heater showing parts and portions broken away and in section approximately along the line 1 1 of Fig. 2, and Fig. 2 is a plan view of my gas heater showing parts and portions broken away and in section approximately along the line 2-2 of Fig.f1.

Similar characters of reference refer to similar parts and portions throughout the views of the drawings.

The base member 1, air and fuel inlet member 2, fuel inlet valve 3, fuel distributing member 4, burners 5, main heater supporting bracket 6, central heater support '7, lower heater base plate 3, reflector member 9, hood 10, cover plate 11 and mantles 12, constitute the principal parts and portions of my gas heater.

The base member 1 is preferably a casting in spider form as shown. It is provided with a hollow upwardly extending central portion 1a which is very simple and economical of construction,`

is internally threaded and communicates with the air and fuel inlet portion 2 whichris positioned at right angles thereto and which is inthe conventional form of inlet for'air and gas for fuel purposes provided with an adjusting plate 2a in the'conventional form. The inlet for'the fuel is also provided'with a valve 3 in the conventional manner for regulating the quantity of fuel relatively to the air. Mounted in the upper end of the portion 1a by means of threads 6a is the mainl heater bracket 6 which is provided with a flange 6b at its lower side and a flange 6c at its upper side. To these flanges 6b and 6c is secured by welding, soldering or otherwise the fuel distributing member 4 which is bowl shaped as shown and with a straight plate 4a at its upper side, thus providing a circular distributing member. Mounteclin the'upper side is a circular row of burners 5 which are preferably of'grid form as shown.

`The upper end of the bracket 6 isinternally screw threaded in which is mounted the lower end of the member '7 which is screw threaded to t therein. This member 7 is provided with a flange 'la spaced from its lower end and upon which is' Vmounted the plate 8-which is circular in form and extendsA outwardlyv past the edgeof the distributing member 4 and on the outer edge of which is mounted a circular band 8a which extends downwardly and leaves a space between its lower edge and the outer edge of the member 4 to permit circulation of air upwardly to the burners and mantles. This plate 8 is provided with openings slightly larger than the burners 5 positioned immediately above each of the burners to permit the flame to pass upwardly and surround each of these openings and upwardly extending L-shaped flanges 8b which serve as holders for the lower end of the mantles 12.

Secured on the upper edge of the plate 8 inwardly from the mantles is the reflector member 9 which is provided with outwardly extending p0rtions 9a which extend outwardly intermediate the mantles, thus forming reflectors back of and at each side of these mantles and extending outwardly some distance, all as shown best in Fig. 2 of the drawings.

The member '7 extends upwardly to a position even with the upper end of the mantles 12 and on the upper end is mounted a hood member 10 and supported by means of a nut 7b. This hood member 10 extends considerably past the mantles and its upper side is tapered downwardly so as to cause the heat to be directed downwardly as it passes from the heater. This hood member is provided with openings to receive the upper reduced portions 12a of the mantles 12 for supporting the upper ends of the mantles in position. Secured abovethe hood 10 in spaced relation thereto by means of spacers 11a and screws 11b is the cover plate 11 which serves to direct the heat outwardly which may pass through the openings around the mantle portions 12a and further serves as a. support for the handle llc for carrying the heater. l Y t The operation of my gas heater is as follows: The fuel is taken in through the valve 3. Air is taken in through the openings in the plate Y,2a

` and passes substantially through the member 1a,

distributing member 4 and burners 5, combustion taking place on the burners 5 and heating the radiant mantles 12, and heat is thrown outwardly by the reflector 9 and extended .portions 9a in circular direction clear around the heater,

vthe hood 10 directing the upper portion downwardly and outwardly so as to provide great efficiency and provide forheating'near the floor clear around the heater.

Though I have shown and described a particular construction, combination and arrangement of parts and portions, I do not wish to be limited to this particular construction, combination and arrangement but desire to include in the scope of my invention the construction,

L.. combination and arrangement substantially as set forth in the appended claims.

Having thus described my invention,` what -I claim asnew and desire to secure by Letters Patent is: n

1. In a gas heater, a combination supporting y frameand-fuel distributer, an annular vertical row of burners positioned on the upper side of said distributer., a radiant mantle positioned over each burner, a. circular reflectorpositioned back of the mantles, said circular reflector provided with a. plurality of outwardly extending portions extending outwardly between said mantles.V

2. In a gas heater, av combination supporting frame and fuel distributer, an annular vertical row of burners positioned on the upper side of said distributer, a radiant mantle positioned over each burner, a circular reflector positioned back oi' the mantles, said circular reflector provided with a plurality of outwardly extending portions extending outwardly between said mantles, and a hood positioned over said mantles extendingr past the outer sides thereof with a downwardly flaring portion outwardly of said mantles. y
